A forest is a piece of land with many trees. Many animals need forests to live and survive. Forests are very important and grow in many places around the world. They are an ecosystem which includes many plants and animals.
Temperature and rainfall are the two most important things for forests. Many places are too cold or too dry for them. Forests can exist from the equator to near the polar regions, but different climates have different kinds of forests. In cold climates conifers dominate, but in temperate and tropical climates forests are mainly of flowering plants. Different rainfall also makes different kinds of forest. No forests exist in deserts, just a few trees in places where their roots can get at some underground water.
